SPECIFICATION forming part of Letters Patent No. 262,039,dated August 1,1882.

Application filed March 27, 1882. (No model.) i

To all whom it may concern Be it known that I, GIDEON HAYNES, J r., ofBoston, in the county ofrSuftolk, State of Massachusetts, have inventeda certain new and useful Improvement in Guns, of which the following isa description sufficiently full, clear, and exact to enable any personskilled in the art or science to which my invention appertains to makeand use the same, reference being had to the accompanying drawings,forming a part of this specification, in which- Figure l is a sectionalside elevation, showing a hammer set at full-cock. Fig. 2 is a sectionalbottom plan; and Fig. 3, an isometrical perspective view of thebody-pin, collet, arms, and hammer-levers detached from the gun.

Like letters of reference indicate corresponding parts in the differentfigures of the drawm s.

li/Iy invention relates to that class of breechloadingfire-arms in whichthe breech is dropped to open the gun for the purpose of loading orinserting the cartridge; and it consists in a novel construction andarrangement of parts designed to constitute an automatic or selfcockin gmechanism, as hereinafter more fully set forth and claimed, by which asimpler and more efl'ective device of thischaracter is produced than isnow in ordinary use.

In the drawings, A A represent the barrels; B, the cartridge or shell 0O, the hammers or striker-levers; D, the body-pin, and E the collet.

The pin is squared, and fits a corresponding hole in the collet, and isprevented from turning or revolving in its seat by means of the teeth orprojections a a, which interlock or engage with the hook or projection mon the rear of the stud or dog Gr.

Projecting rearward and slightly downward from the pin, and fittedrigidly to the same, are two arms or levers, H H, outside of which, onthe ends of the pin, are two elongated washers or sleeves, d d, to whichthe breech of the gun is jointed.

' The arms H H are provided with square holes in their larger or forwardends, in which the square pinD is fitted, the arms being thus preventedfrom turning on the pin, but easily disconnected therefrom wheneverrequired. The hammers or striker-levers O C have their forward ends, a,so formed as to extend under and engage the arms H when the breech islowered, and are designed to be pivoted at n in the lock mechanism. alsodesigned to be provided with the ordinary mainsprings, and also withsears or catches, which engage with the vents or notches z zin the usualmanner; but these parts, and also the other parts of the lock mechanism,as well as the breech and stock of the gun, have been omitted in thedrawings, it not being deemed essential to show them in order to have afull understanding of the nature of my im- IJIOVBIDGllt, the simplicityof which renders an elaborate description unnecessary.

The breech of the gun being hinged or pivoted *to the body by the pin1), itwill be obvious that when the gun is opened to insert thecartridges the rear endsof the barrels will be raised or tilted,or thebreech will be dropped and pass through the arc of a circle of which thepin is the center, thus bringing the elongated portions 00 of the hammerG into contact with the fixed arms H H, and causing the parts to assumethe position shown in Fig. 1, or cooking the gun, after which the breechmay be closed and the gun fired in the usual manner.

It will be obvious that instead of providing the pin with two sleeves,d, as shown in Fig. 3, a head may be formed on the pin to replace one ofthese. It will also be obvious that'my improvement is equally welladapted to either single or double barrel guns.

- I am aware that guns have heretofore been constructed which cock bymeans of the body or hinge pin, or by means of mechanism connecteddirectly therewith, as the breech is dropped to insert the cartridge,and therefore do not claim the same, broadly; but,

Having thus explained my invention, what I claim is In a drop-breechself-cocking gnn,the pin D, arms H 'H, collet E, and sleeves d d, incombination with the dog G and levers O G, constructed, combined, andarranged to operate substantially as specified.
